JAMES T. OARITHERS, OF MORNING SUN, IOWA.

Patented March 30, 1909.

Be it known that I, JAMES T. Cnnrrnnns, I a citizen of the UnitedStates, residing at Morning Sun, in the county of Louisa andImprovements in Tires, of which the follow- 3 ing is a specification.

This invention relates to supplementary 1 tires for vehicle wheels, andthe object of the l whereby an ordinal vehicle wheel maybe i sides maybe cut at an angle toward each readily provided wit 1 a wide bearingface or tread, and which may be quickly and securely invention is toprovide a supplementary tire posltioned upon the wheel, and readilydetached therefrom when desired.

To these and other ends the invention rc sides in the novel constructionand arra igcment of parts hereinafter fully described and claimed. I

In the drawing, Figural is a perspective 4 view of a vehicle wheelprovided with the l. supplementary tire of my construction and l havlngmy improvements, and Fig. 3 is a i sectional view on the line "22 ofFig. 1, looking in the direction of the arrows. Fig. 1 3 is 'a detailperspective view of one of the l lugs. Fig. 4 is a view of the blankfrom which the lug is formed.

In the drawing the numeral 1 designates 5 a vehicle wheel of theordinary construction, and is shown as a means to illustratc'the apiplication of my invention. i

The supplementary tire comprises a pair of segments 2and 3, constructedpreferably of flat metal of any required width and of the necessarylength to encompass the wheel 1. Each of the segments 1 and 2 isprovided with l a plurality of retaining and bracing lugs, arranged inpairs and located at a distance from each other equaling that of thewidth of the felly and tire of the vehicle wheel. "As clearlyillustratedin Figs. 3 and 4 of the draw 3 ings these lugs ale constructed of asingle sheet of metal, stamped in a shape to provide a substantiallongitudinal portion, creased at 1 its center and at vertical pointsfrom its sides equaling one half of the length and width of the bodyorcentral portion 5 of the sheet of metal. The lower creasefrom thecentral line of the sheet of metal is slit at B, and the sheet isprovided with vertical and horizontal scores, while the upper portion ofthe other. In forming the lug the rear portion forming the back orabutment face 4 and the sides 6 are bent upon the central longitudinalline C. The extension of the trian ular sides 6 are folded upwardly uponthe ines l), and the triangular sides 6 are then folded inwardly overthebase 5 which is accurate upon the line E, the triangular sides lyingadjacent the edges of the base while the exi tensions 6 extend entirelyoverthe base 5 and have their. ends meeting at the central portion ofthe base. are provided within the base 5 and the side members 6. Thesemembers aline with each other and are adapted for the reception ofretaining elements whereby the lugs are secured upon the segments 2 and3.

The lugs provided upon the meeting ends of each of the segments 1 and 2are of a construction similar to that just described, but have theirtriangular outer sides or meeting faces provided with slots orperforations Suitable perforations adapted for the reception of suitablebolts 7 and securing elements 8'. It will be noted by referring to Fig;2 of the drawings that I the securmg elements 8 have one of their Iedges lying normally upon the areuate base portion 5 of the retainingand bracing lugs, thus afi'ording aneflicient lock for the nut wherebydisplacement or movement of the i nut is entirely prevented, it beingunderstood that the nut is first positioned upon the base 1 adjacent tothe openings in the side of the lug and the bolt 7 is inserted throughthe openings of the lug and screwed into the nut.

In assembling my improved supplementary tire upon a vehicle wheel, onesection of the tire is first. positioned upon the wheel, the engagingand retaining lugs embracing each side of the folly of the wheel. Thesecond section of the supplementary tire is likewise positioned upon theopposite portion of the wheel, and the bolts 7 are inserted within theperforations provided by the lugs at the extremities of the sections andengage with the nuts 8, thus forcing the sections toward each other andinto tight engagement with the tire-of the wheel, and the lugsintosecurv engagement upon the faces of the telly of the wheel.

It will be noted by reference to Figs. 1 and 2 of the arcuate drawing,that the base pol-- tions 5 of the lugs extend to the outer er gcs ofthe supplementary tire, and that by the constr-uction of the lugs in thepeculiar manner heretofore described, great strength is lUU mehtarytires, and the abutinentvface of the lug engaging with the felly of thewheel receives the strain and the strain thus received is resisted bythe'felly of the wheel. The lugs iieing arranged o posite each other, oneach side of the felly oi" the wheel, strain on a lug upon one side ofthe supplementary tire and imparted to the felly is resisted by the 0osite lug, and a strong and thorou hly e cientsupplementary tire isprovidet by this peculiar construction and arrangement of arts.

rom the above description it will be noted that I have provided a strongand durable construction of vehicle wheels, one

which is easily ap lied to or detached from an ordinary velnc e wheel,which provides means for securely connecting the sections andeffectively retains the sections in locked position with each other, andwhich also provides for the ready separation of the sections of the tirewhen desired.

Havin thus described the invention what is claimer as new is:

I. A supplementary tire for vehicle wheels,

comprising a air of segments having a series of retaining and brrjnglugs having the faces of the felly of the wheel, the ugs at the meetingedges of the segments being 3 provided with openings adapted for the reiof t ie'l'ug and to meet at the center of the 1 lug, the portion of themetal above the slits ception of retaining elements, whereby thesegments are detacl'iahly secured together.

2. A supplementary tire for vehicle wheels, comprising a pair ofsegments having a se 5 -ries of j'retammg and bracing lugs having;arcuate faces to correspond with the curva- 3 ture of the segmentsarranged in pairs spaced r o 'posite each other upon the inner faces ofj tl ie segments and adapted to en age each face of the folly of 'thewheel, the ugs eomprising a' telly abutment face, a base by which it issecured to the segments and triangular sides connecting the face andbase portion, the lugs at the meeting edges of the segments havingtheir-sides provided with face of the tire in pairs spaced apart for thereception of the fellies of a wheel, said lugs comprising a fellyengaging face, a base por tion, secured to the supplementary tire and apair of triangular sides connecting the face and the base portions ofthe lug, the base portion of the lrw extending from the felly engagingface of the lug to the outer edges of the sup lementary tire.

4.. A ug for supplementary tires for vehicles, stain ed from a sheet ofmetal, folded to present a nick and a rounded base, the ends of the backand the rounded base folded to present sides and having their lowerportions slit andada ted to lie upon the base.

3. A lug or supplementary tires for vehicles, comprising a sheet ofmetal provided with a rounded base and adapted to be foldedlongitudhiallyof its center and to be slit near its ends to the center,-said slit portion adapted to be folded over'the lower portion ada )tedto he cut at an angle from the vertical line to the central longitudinalline ofthe in and to form the sidesof the lug.
